Many free e-mail programs are targeting consumers, including 1on1mail, LokMail, PrivacyX.com and ZixMail.

PGP, which Zimmermann sold to Network Associates in 1997, now boasts about 7 million users. Most of them, however, are “die-hard Phil fans and encryption gurus,” says Allison Taylor, PGP director of product marketing for Network Associates.
